+ * TODO:
+ * Edit the "Localization Cleanup (Release Build)" build script phase after
+ * multi-language support is completed and released.
+ *
+ * Note:
+ * - Localization is not available for the Staging configuration, which is used by `UITest`.
+ * - When the functionality is finished, the script should:
+ *    • Remove bilingual content only for Staging.
+ *    • Eliminate the Debug configuration check.
